The applicatoryliquid may comprise hair oil, a hair-setting liquid, a hair-curlingliquid, a hair-straightening liquid, or virtually any other desired typeof applicatory liquid, although frequently it may be water applied tothe persons hair in order to facilitate combing and properly positioninga plurality of strands of hair. However, it should be clearly understoodthat the invention is not limited to any particular applicatory liquid.

Also, it should be understood that, in certain preferred exemplary formof the invention, the hair-grooming device may take the form of a comband the accompanying drawing of the present application illustrates thisparticular form of the hair-grooming device which is to be considered asrepresentative of a number of other types of hair-grooming devices whichmay be employed in lieu thereof, such as various other types of combs,various types of brushes, and the like. Therefore, it should be clearlyunderstood that the invention is not specifically limited to theparticular type of comb illustrated in the accompanying drawing, butthat the invention should be broadly construed as covering the varietyof different types of hair-grooming devices as referred to brieflyhereinabove.

With the above points in mind, it is an object of the present inventionto provide a novel hair-grooming device having controllably activatableand inactivatable liquid-applying means of the character referred toherein generically and/ or specifically, which may include any or all ofthe features referred to herein, either individually or in combination,and which is of extremely simple, inexpensive construction suitable forready mass manufacture at extremely low cost per item whereby to be con-States Patent O 3,456,658 Patented July 22, 1969 ducive to widespreadproduction, distribution, and use of the invention for the purposesoutlined herein.

Further objects are implicit in the desired description which followshereinafter (which is to be considered as exemplary of, but notspecifically limiting, the present invention), and said objects will beapparent to persons skilled in the art after a careful study of thedetailed description which follows.

For the purpose of clarifying the nature of the present invention, threeexemplary embodiments of the invention are illustrated in thehereinbelow-described figures of the accompanying single drawing sheetand are described in detail hereinafter.

FIG. 1 is an elevational view looking at one surface or face of oneexemplary embodiment of the present invention in the form of onerepresentative type of comb having one representative exemplary type ofcontrollably activatable and inactivatable liquid-applying means forcausing the coarse-toothed portion of the comb to be capable of applyingand disseminating a desired type of applicatory liquid on a plurality ofstrands of hair as said coarse-toothed portion of the comb is combed andpassed through a quantity of hair and along the length of said pluralityof strands of hair.

FIG. 2 is a fragmentary sectional view taken substantially along theplane and in the direction indicated by the arrows 22 of FIG. 1.

FIG. 3 is a fragmentary cross-sectional view taken substantially alongthe plane and in the direction indicated by the arrows 3-3 of FIG. 1.

FIG. 4 is an enlarged fragmentary view in elevation with respect to afew portions of the illustrated apparatus and broken away so as to showthe remainder of the apparatus in section substantially along the planeindicated by the arrows 44 of FIG. 6 and of FIG. 7. This view shows boththe discharge or communication valve means between the liquid reservoirchamber means and the discharge passage and the filling valve meansbetween the exterior filling location and the interior of said liquidreservoir chamber means in closed relationship.

FIG. 5 is a view similar in many respects to FIG. 4 but illustrates thedischarge or communication valve means in the open relationship which itassumes as a result of manual opening operation of the longitudinalhollow tubular member embodied in both of said valve means.

FIG. 6 is a view taken substantially along the plane and in thedirection indicated by the arrows 6-6 of FIG. 4.

FIG. 7 is a greatly-reduced-size perspective view of the completeembodiment of the invention shown in FIGS. 1-6 inclusive.

FIG. 8 is a view similar in certain respects to the bottom portion ofFIG. 4 and similar in certain respects to the upper portion of FIG. 5.However, it should be noted that this view illustrates a modified formof the invention which differs from the first form illustrated in FIGS.4 and 5.

FIG. 9 is a fragmentary, partly-broken-away and partly sectional viewillustrating a modified type of top closure cap means for closing thetop opening of the longitudinal hollow tubular member and comprising aportion of the filling valve means for filling the interior of theliquid reservoir chamber means.

Generally speaking, the present invention comprises a hair-groomingdevice which, in the exemplary first form of the invention illustrated,takes the form of a longitudinal comb, such as is generally designatedby the reference numeral 20, which has a longitudinal body portion 22which is provided with a plurality of longitudinally adjacent, laterallydirected projection elements 24 carried along one outer edge surface 26of said body portion 22 and laterally extending therefrom for manuallycontrolled hair-combing and hair-grooming passage through a plurality ofstrands of hair (not shown).

In other words, in the exemplary first form of the inventionillustrated, the hair-grooming device comprises the comb 20, which hasthe longitudinal body portion 22 carrying said projection elements 24,which take the form of a set of coarse comb tooth elements 24 shown atthe left of the device in FIG. 1 and a set of relatively fine comb toothelements 24 carried by the right portion of the comb as shown in FIG. 1.

The body portion 22 is provided therein with liquid reservoir chambermeans 28 adapted to contain an applicatory liquid such as water or anyother desired type of liquid which is to be applied to a persons hair.

The comb 20 is provided with applicatory egress means 30 for use infeeding liquid onto a persons hair as the comb teeth 24 are drawn orcombed therethrough. In the exemplary first form of the inventionillustrated, said applicatory egress means 30 comprises longitudinaldischarge passage means 32 carried along the bottom of at least one sideof the longitudinal body portion 22 and a plurality of longitudinallyspaced egress apertures 34 carried by the edge 26 of the body portion 22in a position such as to communicate the exterior of the comb 22 and theinterior of the longitudinal discharge passage means 32 at a pluralityof locations positioned between adjacent comb teeth 24 along at least aportion of the complete length of the full assembly of the plurality ofcomb teeth 24in the example illustrated, said portion comprisingslightly more than the left half portion of said comb teeth 24 where thecoarse comb teeth are located.

The device also includes manually controllably operable discharge andcommunication valve means effectively connected between the reservoirchamber means 28 and the discharge passage means 32. In the exemplaryfirst form of the invention illustrated in FIGS. 1-7, one exemplary formof such manually controllably operable discharge and communication valvemeans is generally designated by the reference numeral 36 and is of atype which normally is adapted to be maintained in closed relationship,such as is best shown in FIGS. 4 and 6, until controllably manuallytemporarily operated into open relationship, such as is best shown inFIG. 5, which causes water or other liquid to be fed from the hollowinterior of the reservoir chamber means 28 through the apertured valveseat 38 connected between the reservoir chamber means 28 and thedischarge passage means 32, I

whereby to effectively fill said discharge passage means 32 with thewater or other liquid.

Upon completion of the filling of the discharge passage means 32 withwater or other liquid, normally the closed bottom portion 40 of thecommon hollow tubular member, generally designated by the referencenumeral 42, is effectively manually moved from the open relationshipshown in FIG. 5 into the closed relationship shown in FIGS. 4 and 6 sothat said closed bottom portion 40, which effectively comprises anddefines a movable valve member, is effectively inserted into thepreviously-mentioned apertured valve seat 38 and fully sealingly closessame in the manner most clearly shown in FIG. 4. Following this, thecomb may then be applied to ones hair by combing the coarse-toothed combelements 24 through a plurality of strands of hair, which will, ofcourse, allow the water or other liquid to be fed outwardly through theplurality of egress aperture means 34 and outwardly onto said strands ofhair in a relatively evenly disseminated manner along the lengthsthereof whereby to make it possible to greatly facilitate a hair-combingand hair-grooming operation by rendering the plurality of wetted hairstrands much more compliant to the constraint applied thereto by thecomb teeth 24.

The comb 20 is also provided with manually controllably operable fillingvalve means eflectively connected between an exterior filling locationand the interior of the previously-mentioned reservoir chamber means 28for use in filling said reservoir chamber means 28 with a desiredapplicatory liquid, such as water or any other applicatory liquid, whensaid filling valve means is controllably manually temporarily opened.

In the exemplary first form of the invention illustrated in FIGS. 17,the filling valve means referred to above is generally designated by thereference numeral 44 and is also carried by the previously-mentionedcommon hollow tubular member 42 (which comprises a portion of thepreviously described discharge and communication valve means 36) andcomprises a top opening 46 into the upper end of said common hollowtubular member 42 provided with a manually engageable and disengageableclosure cap means 48 and positioned at said previously-mentionedexterior filling location, such as generally designated by the referencenumeral 50, and further comprising lateral aperture means 52communicating the hollow interior 54 of the tubular member 42 with thereservoir chamber means 28.

Thus it will be seen that whenever the closure cap means 48 isdisengaged from the closed relationship shown in FIGS. 1, 4, and 5 to anopen relationship, any desired liquid may be fed through the top opening46 into the hollow interior 54 of the tube 42 and thence out through thelateral apertures 52 into the reservoir chamber means 28 for fillingsame. Upon completion of such a reservoir chamber filling operation, theclosure cap means 48 may then be forcibly re-engaged with the topopening 46 in the closed relationship shown in FIGS. 1, 4, and 5.

It should be noted that in the exemplary first form of the invention,the closure means 48 takes the form of a resilient tapered conicalinsert member 56 preferably made of rubber, plastic, various elastomericor other compressible materials and adapted to be forcibly resilientlyinserted into resiliently frictionally retained closing relationshipwithin the top opening 46, as best shown in FIG. 4, where it will befrictionally resiliently retained until it is forcibly disengagedtherefrom.

In order to prevent inadvertent loss of the closure cap 48 in theexemplary first form of the invention, it is shown as being providedwith a flexible connection and retaining strap 58, which is fixedlymounted by a resilient mounting ring 60 positioned in a shallowcircumferential groove 62 immediately below the upper end of the tubularmember 42.

The previously-mentioned discharge and communication valve means,generally designated by the reference numeral 36, is adapted to benormally held in the closed relationship best shown in FIG. 4 by reasonof the provision of a locking projection 64 carried by the tubularmember 42 and a retaining locking recess 66 and lip portion 68 definedby the body portion 22 of the comb 20 and normally rotatably receivingsaid lockting projection 64 therewithin for rotation between the lockingrelationship clearly shown in solid lines in FIG. 4 and shown in phantomlines in FIG. 6, where said locking projection 64 underlies a portion ofthe locking lip 68 within the locking recess 66 so as to positivelyprevent the entire tubular member 42 from upward movement. However, thelocking lip 68 is provided with a rotata'bly displaced egress slot means70, such as it most clearly shown in FIG. 6, which makes it possible tomanually rotate the entire tubular member 42 in a clockwise direction asviewed in FIG. 6 until the locking projection 64 lies immediately belowand in vertically aligned relationship with respect to said egress slotmeans 70, after which the entire tubular member 42 may be manuallylifted directly upwardly in a manner such as to cause the lockingprojection 64 to pass at least partially vertically upwardly through theegress slot means 70 into a position such as is partially shown in FIG.5. This vertical movement unseats the closed valve member 40 at thebottom of the tube 42 from the apertured valve seat 38 and effectivelyopens the main discharge and communication valve means 36 in the mannerbest shown in FIG. 5. The valve-closing 'and valve relocking operationis essentially the reverse of the unlocking and valve-opening operationjust described and, therefore, will not be described in detail.

It should be noted that normally liquid will feed from the dischargepassage 32 through the egress apertures 34 when the corresponding leftcomb teeth 24 are combed through a persons hair even though the valve 36has been previously closed in the manner described hereinbefore. This isso because of the fact that the small egress apertures 34, which arevery nearly of capillary size, will have water or liquid extendingdownwardly therethrough and forming a lower liquid-air interface oreffective droplet surface immediately below each of the very smallapertures 34 until wiping contact with hair strands occurs during ahair-combing operation. This will, of course, remove each such dropletfrom the lower end of each of the very small egress apertures 34 andwill allow additional liquid to feed downwardly from the dischargepassage 32 for (a repetition of the type of liquidapplying andliquid-discharging o eration just described.

However, upon completion of a hair-combing operation or prior to ahair-combing operation when no wiping contact of hair strands with eachsuch liquid droplet at the bottom of each of the very small egressapertures 34 occurs, the liquid will not be discharged but will beeffectively retained as a result of surface tension and capillary actioneffects.

Additionally, it should be noted that no problem is encountered in aliquid-applying and liquid-discharging operation, as described above, inconnection with the necessary air to replace the volume of liquiddischarged through the egress apertures 34. This is so because of thefact that the comb 20 has its physical orientation and position movedsubstantially during the hair-combing operation and this will normallyallow at least some of the apertures 34 to function in a reverse manneras effeective air vents to allow air to enter the discharge passage 32to replace the volume of the liquid applied and discharged throughothers of the egress apertures 34. However, if it is desired to makeseparate provision for the entry of such replacement air, a verysmall-diameter air vent may be positioned at any desired locationcommunicating ambient atmosphere with the interior of said dischargepassage 32. Normally this should be made of sufliciently small diameterto positively prevent the egress of liquid therefrom while stillallowing the entry of air therethrough and preferably it should bedirected upwardly or positioned at a relatively high level as comparedto the egress aperture means 34 to avoid any possible interference. ForeX- ample, such an air vent aperture might be positioned at a locationsuch as is indicated in phantom at 72 in FIG. 1, although the inventionis not specifically so limited.

Also, it should be noted that, if desired, the comb teeth 24 may beapplied to, and combed through, a persons hair while the valve 36 isopen in a position such as is indicated in FIG. 5 or perhaps in aposition partially closed from that shown in FIG. 5 but not fullysealingly closed as shown in FIG. 4. This will have two major effects.First, it will allow liquid or water to feed through the apertured valveseat 38 into the discharge passage 32 during the very period of timewhile the liquid or water is being discharged through the egressapertures 34 onto the persons hair during a hair-combing operation and,in addition, will prevent any problem of volume replacement within thedischarge passage 32 of the discharge liquid since said discharge liquidwill be replaced with additional liquid from the reservoir chamber means28, which may be provided with a very small-diameter air vent of its ownat any suitable location such as that indicated at 74, for example,although not specifically so limited, and which normally would be of adiameter small enough to allow the entry of air while preventing egressof water therefrom. Also, it should be noted that other means forproviding replacement air for either the discharge passage means 32 orthe reservoir chamber means 28, or both, and either of a continuouslyoperable type or a controllably operable type may be provided in lieu ofthe arrangements referred to above, if desired.

FIG. 8 illustrates a modified form of the invention, and similar partsare designated by similar reference numerals, followed by the letter a,however. In the FIG. 8 modification, it will be noted that the hollowtubular member 42a has coil compression biasing spring means 76positioned within the recess 78 defined by the cylindrical side wall 80and bottom and top annular retaining lip portions 82 and 84,respectively, with the bottom of said spring 76 pressing against thebottom retaining lip portion 82 and with the top of the spring 76pressing against an annular flange or shoulder 86 integrally carried bythe hollow tubular member 42a. The arrangement is such that the spring76 biasing the flange or shoulder 86 upwardly, normally biases theentire tubular member 42a upwardly into the upper position shown insolid lines in FIG. 8 where the closed bottom portion 40a comprising thevalve member of the discharge valve means 36a normally sealingly closesthe apertured valve seat 38a in the manner clearly shown in solid linesin FIG. 8.

However, when a person manually depresses the upper end of the hollowtubular member 42a into the alternate phantom line position shown inFIG. 8, it moves downwardly against the action of the biasing spring 76and unseats the valve member 40:: from the apertured valve seat 38a, asis indicated in phantom in FIG. 8, and allows water or other liquid tofeed from the reservoir chamber means 28a into the discharge passagemeans 32a in a manner similar to that described hereinbefore inconnection with the first form of the invention. Upon release of themanual downwardly applied force from the upper end of the tubular member42a, the biasing spring 76 will return it to its upper extreme position,as shown in solid lines in FIG. 8, where the discharge and communicationvalve means 36a is closed and where the entire apparatus is in aposition analogous to that shown in FIG. 4 of the first form of theinvention. The closure cap means 48a functions in substantially the samemanner as that shown at 48 in the first form of the invention and,therefore, no further detailed description thereof is thought necessaryor desirable.

FIG. 9 illustrates fragmentarily a modified type of closure cap meanswhich is generally designated by the reference numeral 48b and which iscapable of being employed as a replacement for the closure cap means 48of the first form of the invention or the closure cap means 48a of thesecond form of the invention.

It should be noted that the modified cap 48b shown in FIG. 9 comprises ahollow resilient slip-over cap member having a resiliently deflectableouter encompassing bottom lip portion 88 adapted to be forciblyresiliently slipped over a corresponding top flange portion 90 of thehollow tubular member 42a surrounding the top opening 46b and tofrictionally resiliently retained thereby in closing relationship acrosssaid top opening 46b in the manner clearly illustrated in FIG. 9.

The modified closure cap means 48b is also provided with a flexibleretention strap 58b similar to that of the first form of the inventionand having an elastic mounting ring 60b mounting same with respect tothe upper end of the hollow tube 42b, all in the manner similar to thatclearly disclosed in FIGS. 4 and 5 of the first form of the invention.

It should be noted that the specific valving arrangement for each of thetwo valves 36 and 44 of the first form of the invention, and anycorresponding structural elements of the modified forms of theinvention, may be altered somewhat from the specific forms illustratedand still lie within the broad scope of the present invention. This isalso true with respect to the locking means, the closure cap means, andstructural elements associated with said two valves and the means formounting and operating same. In other words, certain variations of sameare contemplated and are intended to be included within the broad scopeof the present invention.

It should be understood that the figures and the specific descriptionthereof set forth in this application are for the purpose ofillustrating the present invention and are not to be construed aslimiting the present invention to the precise and detailed specificstructure shown in the figures and specifically described hereinbefore.Rather, the real invention is intended to include substantiallyequivalent constructions embodying the basic teachings and inventiveconcept of the present invention.
